Why people are declared dead when the brain stops functioning even when the heart is still beating?

When the brain stops functioning, vital bodily functions controlled by the brain cease, leading to irreversible damage. The brain requires a constant supply of oxygen and nutrients, which are delivered through blood flow controlled by the heart. Despite the heart continuing to beat, without brain function, the body cannot sustain life.


When the heart stops beating due to interference of it's electrical impulse?

When cardiac muscle contraction is out-of-sync, causing chaotic contractions across the whole of the heart, preventing it from beating and pumping blood, this is called fibrillations. This typically happens when a myocardial infarction (blood clot leading to a heart attack) blocks blood to the coronary arteries, resulting in hypoxia to certain muscle cells. Then, after medical intervention, when the coronary arteries are unblocked and blood supply returns, some cardiac tissue beats out of sync with the rest of the heart, resulting in fibrillations. The usual treatment for this is the use of a defibrillator. This device sends a strong electrical signal into the heart, stopping it momentarily. Then, the brain can send a signal to the SA (sinoatrial) node of the heart to restart it again, so that the heart beats properly again.


What would cause blood flow to stop?

if the heart stops


What happens when your blood doesn't flow?

You Die!!!!!!!!!!!!!! ============= When your blood stops circulating, it means your heart has already stopped beating. While not always 100% fatal, it will be unless your heart starts beating again very quickly.


If the blood supply to the myocardium stops what happens?

that part of the heart tissue dies
